How to create root node in the spacesStore?

[davidsun]

I have a data model as following and now I want to create root node in the spaces store, just like out-of-box Catetory_root in the contentModel.xml.

I get spaces store in the following way:

       List<StoreRef> stores = nodeService.getStores();
       StoreRef store = null;
       for(StoreRef s : stores) {
          if(s.getProtocol().equalsIgnoreCase(StoreRef.PROTOCOL_WORKSPACE) && s.getIdentifier().equalsIgnoreCase("SpacesStore")) {
             store = s;
             break;
          }
       }
‍‍‍‍‍‍‍‍‍‍

but nodeService only have function to create NodeRef under another NodeRef. How can I create a root node in the Spaces Store?


Thank you!

You just need to get root node of the space store

   NodeRef rootNode = nodeService.getRootNode(StoreRef.STORE_REF_WORKSPACE_SPACESSTORE);

Thank you! You information is very useful. following I still have the problem to create node in SpacesStore root. The code is like this:

<java>
       NodeRef rootNode = nodeService.getRootNode(StoreRef.STORE_REF_WORKSPACE_SPACESSTORE);
       QName nodeTypeQName = QName.createQName(NAMESPACE_HIGHROADS_CONTENT_MODEL, TYPE_HR_SEARCHFIELD_ROOT);
       ChildAssociationRef childAssRef = nodeService.createNode(rootNode, ContentModel.ASSOC_CONTAINS, QName.createQName("{app}searchfields"), nodeTypeQName);
</java>

I get the following exception:

<cite>
org.alfresco.repo.node.integrity.IntegrityException: 01130007 Found 1 integrity violations:
The association source type is incorrect:
   Source Node: workspace://SpacesStore/e909ccce-092e-4bce-a77f-6848dd7b1f42

But if I use "company home" as parent node, it will success.

Any suggestion? Sorry I am new for Alfresco.

Thank you!

I think association type should be sys:children (ContentModel.ASSOC_CHILDREN) instead of cm:contains (ContentModel.ASSOC_CONTAINS). Try this:

        NodeRef rootNode = nodeService.getRootNode(StoreRef.STORE_REF_WORKSPACE_SPACESSTORE);
       QName nodeTypeQName = QName.createQName(NAMESPACE_HIGHROADS_CONTENT_MODEL, TYPE_HR_SEARCHFIELD_ROOT);
       ChildAssociationRef childAssRef = nodeService.createNode(rootNode, ContentModel.ASSOC_CHILDREN, QName.createQName("{app}searchfields"), nodeTypeQName);
